Plan to get a true dual setup fabbed up (mandrel bent stainless steel 3") by a shop in Raleigh. This is the first step! Can't wait to get it done.
 
That's a pretty decent price.. sst headers for the G8 are usually around $800 and another $800+ if you want a sst cat-back (incl. high flow cats). Could go catless, but I'd rather not on a DD.

The stock cats leave a lot to be desired when it comes to flow though...

I did enjoy the statement about the non-cats:

Nice! Be sure to get an engine tune when you're done, it will really wake up that LS1.

I still have dreams of picking up a mint late model WS6 TransAm, love that body style...

LOL, totally missed that. They don't even look at anything on the car around here anymore, they just plug it in and if it's not throwing codes it's a pass. :awe:

Back in the 90's though I would take apart old cat shells and clamp it around the straight pipe so when they stuck the mirror under it looked legit. 😀

I kind of want to wait until I get an LS6 instake and a cam kit before I get a tune...just don't want to pay all that money twice. Will need to get it before April or so though..that is when inspection is due, so need to get cats tuned out.

Because they are required for emissions. They do a visual inspection.

So you'll pass the visual, but will fail the actual emissions test? IIRC even with o2 adapters, the car will never get into the "ready" mode, so they'll get you on the obd.

Unless you program the computer to always be "ready".

Anyway, when I pull cats off my cars I really don't care about fooling anyone. When its time for inspection/smog, put the real stuff back on.

LOL! Awesome. Now I want to buy one just to hang it on my wall.
 
Nice. I just ordered a set of 2" Kooks for the V. Had them coated with Jet Hot 1700 Sterling Silver. I will have to take a pic once they get in.

They scan for codes. I can get the codes tuned out. Plus, this is NC. All the good ol' boys run straight pipes. If you can't find someone to pass it, you're doing it wrong.

😱
 
Just taking the cats out shouldn't increase volume very much. It does add to the noise though.

Nice headers. I wish I could throw some nice ceramic coated long tubes on my 95, but I live in Cali.

Either you can use MIL eliminators which send a false signal back to the ECU so it shows ready in conjunction with a tune, or you can simply have the rear O2s disabled. You are allowed like 2 monitors reporting not ready or something like that and still able to pass emissions.

OBD II emissions takes like 5 seconds, they plug it in, read the screen, good to go, and the car never changes engine speeds or runs funny, so they aren't doing a full OBD II test that would catch the MIL eliminators not responding when the mixture is too rich for the cats anyway.

A full OBD II sweep from a diagnostic scanner like my Solus takes like 5-10 mins and you have to turn the wheel lock to lock when prompted and all kinds of stuff. This would show the fake rear O2s not changing at all when the test fattens the mixture to test cat efficiency and throw rear O2 codes if they actually ran that test, but they dont, because it takes too long 😛
